Definitions

  • the invention relates to an engine mount with hydraulic damping, comprising a working space delimited by a support, a suspension spring and a partition and an compensation space delimited by the partition and a flexible buffer wall, which are connected by a throttle opening and filled with a liquid, and an arranged in the partition, gas-filled chamber, which is closed off from the work area by a circularly delimited disc suspended from an elastic ring membrane.
  • European patent application 0 115 417 relates to an engine mount of the aforementioned type. It is characterized by a good insulating effect when high-frequency vibrations are introduced and by a good damping effect when low-frequency vibrations are initiated of less than 30 Hz. If, however, both types of vibration are introduced in a mixed form, for example when driving over bumps at high engine speeds, the insulation effect is considerably impaired. This is where the invention comes in.
  • an engine mount of the type mentioned at the outset in such a way that when vibrations are introduced, which include both those of a low-frequency spectrum and those of a high-frequency spectrum, in addition to good damping of the low-frequency vibrations, there is a good insulating effect of the high-frequency vibrations .
  • This object is achieved according to the invention in an engine mount of the type mentioned at the outset in that the disc consists of a chain oscillator in such a way that it comprises at least two successive absorber masses lying radially one inside the other, which are elastically secured to one another by an annular membrane.
  • the subclaims refer to advantageous configurations.
  • the function of the engine mount proposed according to the invention is likely to be based on the fact that the mobility of the individual damper masses combined to form a chain oscillator influences one another, the damper masses as a whole being supported on the gas pressure cushion contained in the chamber. Your elastic suspension experiences a constant change depending on the forces that are introduced. This results in good compensation of high-frequency vibrations, and it is of decisive advantage that this advantageous effect also occurs when low-frequency vibrations are simultaneously introduced into the engine mount.
  • the ratio of the total absorber mass and the proportionate mass of the motor is max. Is 0.1 and the ratio of the rigidity of each ring membrane and the rigidity of the suspension spring is max. 1.0. It should be noted that if one of the two parameters is varied, the other parameter must always be changed in the same direction.
  • the coarse tuning can take place on the basis of theoretical calculations, for which a further explanation is not necessary at this point. The fine tuning is reserved for practical testing of the vehicle equipped with the proposed engine mount under normal operating conditions.
  • a further improvement in effectiveness can be achieved if the ratio of the hydraulically effective piston area of the support bearing fixed to the suspension spring and the corresponding hydraulically effective area of each absorber mass is in the range between 1 and 16, advantageously in the range between 2 and 8.
  • the first-mentioned piston surface comprises approximately 2/3 of the surface which results when the underside of the support bearing and the support spring are projected onto a surface which extends transversely to their direction of movement.
  • the latter area includes the correspondingly projected image of each absorber mass, enlarged by 50% of the area of the adjoining ring membrane projected in the same way.
  • All the ring membranes used in the motor bearing proposed according to the invention are designed in such a way that they can be deformed without any appreciable damping work.
  • the mentioned absorber effect is particularly evident.
  • the absorber masses used have a weight of 10-200 g, usually 10-50 g for car engines.
  • a design of the absorber masses and the associated ring membranes deviating from the absolute circular shape is possible. Oval or polygonal designs can therefore be included in the considerations.
  • the 1 comprises the support 1 and the support bearing 4, which are connected by the hollow-conical support spring 2.
  • the support 1 is cup-shaped and connects to the underside of the partition 3, against which it is sealed by the edge-side bead of the buffer wall 6 made of elastic material.
  • the buffer wall 6 and the underside of the dividing wall 3 together enclose the compensation space 7.
  • the working space 5 is essentially delimited by the support bearing 4, the suspension spring 2 and the dividing wall 3. It is connected to the compensation chamber 7 through the throttle opening 8 and, like this, is filled with a liquid, generally with water, to which an antifreeze is added.
  • the space between the buffer wall 6 and the support 1 is vented. As a result, pressure cannot build up in this space when the buffer wall 6 is deformed.
  • the partition 3 contains a gas-filled chamber.
  • the pressure is adjustable and can be above or below atmospheric pressure.
  • the chamber is delimited from the working space 5 by the disks 11, 13 and by the ring-like membranes 10, 15 connecting them like a chain to one another and to the partition.
  • the latter have elastic properties and the disks experience a shift when the pressure in the working space changes . They influence each other depending on their mass, the elasticity of the ring membranes and the frequency of the vibrations introduced.
  • Fig. 2 shows the ring membranes used in Fig. 1 in a half-section.
  • the profile is essentially characterized in that the ring membranes on the opposite sides have axial ring projections 16, 17 assigned to each other in a mirror image and that the radial boundary surfaces of the ring projections have stop surfaces 18 which are associated with each other and the ring projections 16, at a distance. 17 are assigned in mirror image.
  • the axial displaceability of the disks held by the ring membranes is thereby limited to a certain dimension, the value of which is characterized by the mutual contact between the stop surface 18 and the respective opposite ring projection 16, 17.
  • the contact is completely noiseless due to the rounding, which is a great advantage in terms of the desired driving comfort.
